[Field of Application of the Invention] The present invention relates to a strip twisting method in which the strip is twisted (twisted) while the strip material is being fed, and more particularly to a strip twisting method that can improve equipment and strip quality. BACKGROUND OF THE INVENTION For example, in rolling mills, strip material is generally fed with its surface facing upward or downward, ie, in a horizontal state. By the way, if the rolling equipment is equipped with equipment (such as a spiral looper) that accepts the strip with its surface facing sideways, that is, vertically, the strip must be twisted 90° before and after that equipment. Conventionally, as shown in FIG. 1, for example, a method has been frequently used in which the strip 1 is twisted while the path center C 0 remains in a straight line. That is, the strip 1, which has progressed in a horizontal state, is pinched from the horizontal pinch roller 2 to the vertical pinch roller 3 in a 90° twisted state, and is transformed into a vertical state. However, in this conventional method, the relationship between the twist lengths 1 , 1 at both ends of the strip at the twist portion and the path center length 1 is 1 = 1 ≠ 1 , and the strip 1 deforms as shown by an imaginary line.
This deformation of the twist portion has a negative effect on the product shape of the strip 1, and it is necessary to minimize the amount of deformation. Therefore, in the conventional method, the twist span (between the horizontal pinch roller 2 and the vertical pinch roller 3) has to be longer than a certain length, which has the disadvantage that the entire device becomes long. In addition, in this conventional method, the strip 1 is unnaturally deformed, and when tension is applied, surface flaws or bends may occur, which may adversely affect the strip quality. It also has the disadvantage that it cannot be used in continuous equipment. [Object of the Invention] An object of the present invention is to provide a strip twisting method that can shorten the twist span, reliably prevent strip deformation, and contribute to quality improvement. [Summary of the Invention] In the twisting method according to the present invention, the strip curved surface of the twist portion is formed as a curved surface that can be developed into a plane (hereinafter referred to as a developable curved surface), so that the strip maintains a smooth curved surface. It is something. In the first invention, the developable curved surface is twisted in a shape that follows a conical curved surface, and in the second invention, the developable curved surface is twisted in a shape that follows a cylindrical curved surface, which is a method that is easy to put into practical use. (hereinafter referred to as conical guide and cylindrical guide, respectively). The principle of the present invention will be explained with reference to FIGS. 2 to 9. First, the conditions for the conical guide will be explained. FIG. 2 shows the state in which the strip 1 is wound around the cone 4. Assuming that the strip entrance is ACB and the strip exit is A 1 C 1 B 1 , the line segments 1 and 1 are approximately parallel unless the lengths of the line segments 1 and 1 are extremely different. Therefore, 1 − 1 = 1 − 1 ...(1). Therefore, if L A = 1 − 1 L B = 1 − 1 } ...(2) then |L A +L B |=0 ...(3) In other words, the positional relationship between the entrance and exit of the strip is
If formula (3) is satisfied, that is, if the length of the straight line connecting the edges and the center of the plate is the average of the lengths of both ends, then the strip surface is a cone. Can be formed. Next, the conditions for the cylindrical guide will be explained. FIG. 3 shows the state in which the strip 1 is wound around the cylinder 5. In the case of a cylinder, immediately 1 = 1 = 1 ... (4) Expressed by equation (2), L A + L B = 0 or |L A | + | L B | = 0... (5) In other words, the strip If the positional relationship between the inlet and outlet of the strip satisfies equation (5), that is, if the lengths of the straight lines connecting the edges and the center of the plate are equal, the strip surface can be formed as a cylinder. Figure 4 shows the positional relationship between the entrance and exit of the strip using a coordinate system.
Expressing equation (2) with l, = b, entrance and exit angles θ and β), Here, i is i=1 when the y-coordinate of B 1 > the y-coordinate of A 1 and i=1 when the y-coordinate of B 1 < the y-coordinate of A 1 . Therefore, based on equations (6) and (7), the positional relationship (θ, β) of the entrance and exit that satisfies equations (3) (conical guide conditions) and (5) (cylindrical guide conditions) is determined. Let's look for each of them. First, to explain the conical guide, if one of the entrance/exit angles θ and β is fixed and the change in the other is examined, the relationship as shown in FIGS. 5 and 6 will be obtained. From this, θ and β that satisfy equation (3) are
